Background And Objective: People with adult-onset hearing loss (AoHL) are at increased dementia risk. In this study, we explore potential aetiological mechanisms by synthesising the evidence on the association between AoHL and neuropathological, cerebrospinal fluid (CSF), blood and imaging biomarkers of dementia.

Methods: We systematically searched electronic databases from inception to 30 April 2024 for cross-sectional and longitudinal studies, including quantitative data on the association between AoHL and dementia biomarkers.

The valorization of shell-based agricultural waste biomass for biofuel production represents a promising approach within the circular bioeconomy. This study employs a bibliometric analysis to investigate research trends and identify key developments in the field from 1997 to 2023, using data from the Web of Science and VOSviewer for scientific mapping. A total of 1333 research articles were examined, revealing notable shifts in research focus: from pyrolysis and biomass energy (1997-2005) to gasification (2006-2014), and more recently, to enzymatic hydrolysis and lignocellulosic biomass gasification (2015-2023).
